The hemoglobin holoenzyme (active enzyme) is a complex of an iron ion and 4 subunits- 2 hemoglobin alpha and two hemoglobin beta. People with sickle cell disease have mutated beta hemoglobins. The mutation is a single nucleotide exchange, that changes the 6th amino acid of protein primary struture - a Glutamic acid into Valine. This one alteration changes the tree dimentional structure of hemoglobin beta so, that it forms lond fibres that disrupt the normal circular form of the red blood cells.
It would die after harmful substances entered the cell. This would happen because it would burst due to over-bulging.
No, studying the effects of sunlight on the color of paper would be an experiment in qualitative data. Quantitative data is based on numbers, a change in appearance is qualitative data.
Match each biodiversity restoration method to its description we have:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation:using plants to increase biodiversity and food resources
<h3>What are ecological restoration techniques?</h3>
Some examples of induced ecological restoration methodologies are the conduction of natural regeneration, nucleation techniques, enrichment or diversity planting, among others.
In this case, the ecological restoration techniques are:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation: using plants to increase biodiversity and food resources
